The Hertz HMD1 is a mono amplifier designed for one or more subwoofers in a boat’s audio system. It provides the subwoofer with dedicated, powerful amplification and delivers rich, controlled low-frequency sound. The amplifier can operate with a 1 Ω load and deliver up to 1000 W of power. Line-level RCA and speaker-level inputs provide flexibility when connecting it to various audio systems. The auto-power-on function triggered by the speaker signal allows the amplifier to be integrated even when a separate remote power-on wire is not available. The compact housing facilitates installation in confined spaces, while adjustable filters allow you to tailor low-frequency reproduction to the subwoofer and the entire boat’s audio system.
